Porsche 997 Turbo with 600 all wheel horsepower takes on a 600 wheel Corvette ZR-1 from a 40 mph roll
Pretty good race here between two cars both said to be making 600 horsepower to the wheels. The Porsche 997 delivering its power with twin turbo 3.6 liter flat-6 and the Corvette ZR-1 with a positive displacement supercharged 6.2 liter V8. Weight is in the ZR1's favor as the curb weight of the C6 ZR1 is about 3,344 pounds. Depending on what transmission is in the 911 Turbo the weight difference is between 200 and 250 pounds.
The exact modifications are not listed but the 997 turbo has to have upgraded turbos and the ZR-1 some bolt on's. The ZR-1 may be sandbagging as the owner gives the 997TT the hit and is able to catch and pull. Definitely an impressive ZR-1 and the 997TT is no slouch.
There is a bonus race where a C6 Z06 runs the ZR1 and is said to have some mild mods but the owner is REALLY sandbagging. Judge for yourself, great runs.
